Dams profoundly impact the geomorphology of rivers by altering the natural patterns of water, sediment and energy flow in rivers. These changes have a largely negative impact on aquatic and riparian ecosystems upstream and downstream of the dam. Natural dams also impact river geomorphology, although with positive and negative repercussions for aquatic and riparian organisms.
In 2002, the 33rd Binghamton Geomorphology Symposium convened under the theme "Dams and Morphology," and featured invited papers and contributed posters on topics of natural dams, artificial dams, and dam removal. Fourteen of these papers have been included in this volume.
